Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric testing devices, in particular to a testing device for antibacterial and waterproof non-woven fabrics. Background Art

[0002] After the antibacterial waterproof non-woven fabric is produced, its waterproofness is generally tested. Waterproof non-woven fabric is a new type of environmentally friendly material with good waterproof performance, which is composed of fibers and other materials in different proportions. When making it, the non-woven fabric production process is first used to form a fiber mesh through melt blowing, needle punching and other methods, and then a layer of waterproof coating is applied on the fiber mesh. The waterproof coating is used to prevent moisture from entering the non-woven fabric, thereby achieving a waterproof effect.

[0003] At present, when testing the waterproof performance of waterproof non-woven fabrics, they are generally immersed in a water pool for testing. However, waterproof non-woven fabrics are generally made into masks after they are produced, and their waterproof coatings are generally sprayed on the outside of the masks. The immersion testing method cannot effectively simulate the situation where external droplets splash to the outside of the mask when the mask is used. Therefore, it is necessary to design a testing device for antibacterial and waterproof non-woven fabrics to solve the above problems. Utility Model Content
